Motive Gear T8.2-488 Ring and Pinion 4.88 Ratio, 8.2in, 30 Spline

The Motive Gear T8.2-488 (also listed as T82488) is a performance differential ring and pinion gear set with a 4.88 gear ratio. It is made for Toyota 8.2-inch differentials. The set is built for both on-road and off-road use, and the lower numerical gearing helps restore acceleration and pulling power. This is useful with larger tires, heavy towing or hard trail driving.

Key Features:

• 4.88 ratio: 39-tooth ring gear matched with an 8-tooth pinion gear
• Pinion: 30-spline pinion with a 1.57-inch shaft diameter
• Ring gear bolt pattern: 12-bolt
• Material: 8620 steel construction
• Manufacturing: Precision-machined and heat-treated for strength and durability
• Design: Optimized tooth geometry for smooth power transfer and reduced noise
• Fit and function: Built to keep OE-style fit and function

Motive Gear develops its drivetrain components through racing and in-house testing. The goal is long service life under heavy loads and rough conditions. A complete gear setup installation typically also involves a master install kit and proper gear setup (pattern and backlash), which should be done by an experienced installer.
